Nanotechnology is revolutionizing the cosmetic industry by enabling targeted delivery, improved absorption, and enhanced product efficacy at the molecular level. Nanocarriers such as liposomes, nanoemulsions, solid lipid nanoparticles (SLNs), and dendrimers are used to encapsulate active ingredients for skincare, sunscreens, anti-aging, and hair treatments. These formulations ensure deeper skin penetration, controlled release, and increased stability of sensitive compounds like vitamins and peptides. Regulatory challenges remain around safety and transparency, but consumer interest in high-performance, science-backed cosmetics continues to drive nanotech adoption.
